Document Summary

Note: these are questions to help get you familiar with the format and style of the exam. The content of the questions do not necessarily reflect the content that will be on the midterm. You will also be provided with a formula sheet, and the table on pg. To derive the least squares estimator for y , you find m which minimizes n. When the estimated slope coefficient in the simple regression model, 1: r2 = y , 0 < r2 < 1, r2 = 0, r2 > (ssr/tss). You are told that the t-statistic on the slope coefficient is -4. 38. What is the standard error of the slope coefficient: 0. 52, 1. 96, -1. 96, 4. 38. Where is the outcome of a die roll (dice). As n becomes large, is distributed according to the normal distribution, by a certain theorem. Consider a sample of three observations collected from the random variables y and x:
